7 Claims.

My present invention relates to adjustable evacuators.

Embodiments of my present invention, designated adjustable evacuators, possess characteristics of the general nature of half-syphon legs, that is to say, function to form the posterior leg of a syphon, the anterior leg of which is' constituted of an upwardly extending passage with H which my evacuator is connected and serving therewith to discharge a defecator, the evacuator being constructed for adjustment to accommodate varying relative positions of its connection with the anterior leg of the syphon and the connection of the evacuator to the soil pipe or other channel of discharge.

My present invention is a development of my evacuator set forth and claimed in my copending application Serial #7 4,620, filed February 2nd, 1935, and entitled Evacuators.

The general characteristics of my present invention reside in an uppermost portion arranged to have its inflowopening detachably connected to the uppermost portion, i. e discharge of an upwardly extending leg of a lateral outlet type of defecatoror to the uppermost portion, 1. e. discharge of an upwardly extending anterior syphon leg of a non-lateral outlet type of defecator; such uppermost portion includes a weir serving per se as or in conjunction with a wall of the'uppermost portion of the anterior syphon passage or leg as a dam. The evacuator further includes a bulge or elbow formation at an upper portion thereof, whereby upon flow of the efiluent discharged from the defecator, a portion of the quantity of air originally in the bulge or elbow formation, is entrained thereby giving rise to sub-atmospheric pressure of the retained air. My evacuator further includes a downwardly extending central or other intermediate portion, the effective crosssectional area of which is less than that of the uppermost portion of the evacuator, thus providing for a relatively restricted cross-sectional mass of the effluent through such intermediate portion.

Pursuant to my present invention, the defecator further includes an adjustable component part, advantageously an adjustable foot or lowermost portion to afford communication of the discharge opening of the evacuator relative to its inflow opening, thereby in turn affording a range of posinected for the eventual discharge of conducted therethrough.

Further features and objects of the invention will be more fully understood from the following detail description and the accompanying drawing, in which Fig. 1 is a vertical central sectional view of a 5 preferred embodiment of my invention, illustrating the principle of my invention as applied to an adjustable foot serving as the adjustable component part of my evacuator.

Fig. 2 is an elevational view of Fig. 1.

Fig. 3 is a vertical central sectional view of another embodiment of my invention.

Fig. 4 is an elevational view of Fig. 3.

Referring to the preferred embodiment of my invention shown in Figs. 1 and 2, the evacuator It] comprises an uppermost portion H, preferably provided with an enlarged and thickened annular wall encircling its inflow opening l2. Such thickened wall portion H has particular application for its connection with the discharge opening of the upwardly extending syphon leg of a lateral outlet type of defecator, such as is shown in my copending application Serial #749,069, filed October 19th, 1934,entitled Defecator. For other types or embodiments of defecators, such wall construction as indicated at H is suitably arranged, as is understood by those skilled in the art.

In the particular evacuator shown in Figs. 1 and 2, the central and downwardly extending portion l3 has an effective diameter definitely less that of its inflow opening l2 and the portion intermediate the stated component portions includ'es the elbow portion, see its wall I l and therewith combined weir or dam IS. The interior of the elbow portion I6 is designed to have a predetermined volume. in correspondence with the characteristics of the inflow opening l2 and the downwardly extending relatively restricted portion l3, whereby upon discharge of the effluent through the inflow opening l2, effective removal of the air takes place progressively from the interior of such elbow portion to thereby reduce the pressure of such air retained therein, for the purposeof maintaining sufiicient vacuum for initiating and maintaining syphonic action during the stage of discharge of a defecator or the like.

Advantageously, the inner face, see [2a, of the lower portion of the wall [2 extends substantially horizontally and in substantial alignment with the lower wall of the discharge opening ofthe upwardly extending lug of a lateral outlet defecator or of the anterior syphon passage or leg, the discharge of the defecator orthe like including a gradual rising of the effluent above such dam or weir until the efiiuent at the stage of full discharge substantially fills the whole of the inflow opening l2. The provision of the relatively restricted downwardly extending portion l3 serves to advance in time period the complete filling of the effluent at and beyond the inflow opening [2 of the evacuator, thus speeding up the formation of full syphonic action accompanied by the speeding up of the condition of sub-atmosphericpressure of the air retained within the interior of the elbow portion 14.

The lower component portion of my evacuator possesses the general characteristics of maintenance of such full syphonic action, including the preservation of the sub-atmospheric pressure within the upper portions of the evacuator, had advantageously by the formation of a curtain or wall of the eiiiuent effected by the flow of the effluent through the central portion E3 in contact with and downwardly below the projection l6, illuse trated in the embodiment shown in Figs. 1 and 2 as a component part of the adjustable foot or lowermost portion [1 of the defecator.

I-also prefer to dish, i. e. lowerly hollow-out the bottom portion, see Ha, of the foot portion I1, which in cooperation with the discharge outlet 18 serves to create a pool of the effluent having a general level indicated by the dot and dash line l'lb, during the stage of discharge of the'eiiluent through the defecator; it will be apparent, however, that such pool will not be quiescent during thestage of the effluent, at which time the curtain of the eiiluent, as above set forth, creating such pool, causes surges of the pool.

The extent of the dishing of the bottom 11a of the foot portion l1, and the relative location of the surface l 8a of the lowermost portion of the wall of the discharge opening 18 may be varied as desired.

The adjustability of the foot portion II of my defecator, as illustrated in Figs. 1 and 2, is advantageously had by a telescope connection with the, lower end of the central portion I3 of the def-. ecator, as by means of the upwardly extending annular flanged wall l9, desirably including an inwardly extending shoulder, see Illa, for the seating of the lowermost edge, see 3 1, of the central portion l3 of the defecator within such annular flange I9, such telescope relationship affording 'rotary articulation includes; vertically adjustedtelescoped positioning of the foot portion 11, relative tothe upper portion of my defecator, and conversely rotary articulation of the upper portion of my defecator relative to its foot portion I1 7 As is shown'in Fig. 2, the stated face I811. of the wall of the discharge opening l8 of the foot portion I1, is preferably flattened'and disposed in a substantially horizontal plane.

The embodiment of my invention shown in Figs. 3 and i conforms largely to that illustrated in Figs. 1 and 2, and like parts are designated by like reference characters. The embodiment shown in Figs. 3 and 4 illustrates in particular a projection 16a, corresponding in general to the projection l6 of the embodiment shown in Figs. land 2, but extending, advantageously arcuately, toward the central longitudinal axis of the defecator, whereby to more effectually form the curtain of the eiiluent, that is to say, to advance in time the instant of formation'of the curtain, condense the curtain in physical formation during the stage of full discharge and prolong the period of its formation, thereby more effectively preclucl-. ing the entry of air through thedischarge open-1 ing l8 of the evacuator in a direction counter to that of the flow of the eiiluent, and in turn enhancing the discharge of the defecator or other receptacle with which my evacuator is connected.

Coacting with such inwardly directed projection I600, the oppositely disposed wall portion, see I6a, of the leg I! may be contoured in direction and facial formation corresponding to the projection It will be understood that the configuration of the body and other component parts of my evacuator may be varied, such as Z, S or like configuration illustrated in my aforesaid copending application Serial #4,620, combined with an adjustable foot portion or other adjustable component part, for importing articulation to my evacuator for adjustable relationship between its inflow opening and its discharge opening.

A suitable sealing medium is applied in the joint of the relatively articulated portions, whereby upon final positioning of the evacuatQr, i. e., upon completion of its connections atits respective inflow opening and its discharge opening, its joint of articulation including adjusted vertical positioning is sealed against escape of sewer and other unsanitary gases, and also to preclude the entry of air therethrough in possible diminution of the syphonic action;

Whereas I have described my invention by reference to specific forms thereof it will be understood that many changes and modifications may be made without departing from thespirit of the invention.
